The political arm of Senate Republicans has been using the real estate mogul to attract small-dollar donors since May. The National Republican Senatorial Committee has been pushing supporters in emails to purchase Trump koozies, t-shirts, stickers, and other items that say “I’m with Trump.” The emails direct to the committee’s website for donations.

Trump’s recent proposal to ban Muslims from entering the U.S., which was widely criticized by Republican leaders in Congress, hasn’t kept the NRSC from continuing to use the GOP presidential frontrunner for fundraising.

In an email sent Wednesday, the committee encouraged supporters to “claim” the “perfect gift” — a Trump koozie for $12 — “just in time for the holidays!”
